Comfort, what is this thing you call comfort I mean if it sounds good it must feel good too
They are certainly comfortable. I saw you asking about the 598 so if an open set of cans will work for your needs you should consider the DT990 over the DT770 IMO. I have both and love them both but the 990 is better for extended listening and isn't as fatiguing in the highs. The 770 has more impact in the bass due to the closed design but the quantity is comparable with the 990 having a much more airy sound obviously and larger soundstage.
YEA I'm really wanting the dt 990 my self for a good mid bass can, and again I love that I keep hearing about it <3
